Sometimes (into nsPage) an alternative syntax is useful (see an example here and following page:

{{outdent}}
{{lorem ipsum}}
</div>

Opens a div class="tiInherit" style="text-indent=-2em"; following paragraphs will be outdented. The div must be closed at the page end with a </div> tag.

When the text block continues into more pages, please put the template and the closing code following these suggestions:

page section hosting the template section hosting the closing code
first page body footer
following pages header footer
last page header body
